Done both of them already <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" /> The spiders will spider the profile links, but when you click on them, they come up 404. As to the robots.txt file, I've got it down the bare minimum -

User-agent: *
Disallow: /others_pictures/
Disallow: /temp/
Disallow: /phpban/

That shouldn't be stopping any spiders, should it?
